“17S 18S 19S 20S 21S 10S 11S 12S 13S 14S 15S 16S Version” is available for NCM/Li ion/Lifepo4/LTO
All versions can be switched between Lifepo4/Li ion and LTO, and only the welding points need to be changed
No external power supply is required, and the internal energy transmission of the battery is used for transmission. The entire battery pack is in a balanced state.

The modes of NCM(Li-ion) and LFP (Lifepo4) are as follows
24 strings 4A
Applicable string number 10～24S
Applicable battery type NCM/LFP/LTO (ternary/lithium iron/lithium titanate) fully compatible
Power supply range Applicable number of strings The minimum total voltage of the battery pack is greater than 30V, the recommended value: ternary battery≥10 string, iron-lithium battery≥12 string, LTO battery≥20 string
Single unit voltage working range 1.0～4.5V
Voltage balance accuracy &lusmn;1mv (voltage measurement accuracy), &lusmn;1mv (voltage balance accuracy)
Equalization method Patented equalization architecture flying capacitor method, combined with point-to-point energy transfer algorithm for high-efficiency equalization.
Equalization current APP custom setting: 1-4A, due to the use of constant current and constant voltage technology, the equalization current has nothing to do with the battery voltage difference.
Drop detection support
Under-voltage protection sleep voltage The under-voltage sleep voltage can be customized by APP: 1.5-4.2V
Static working current: balance off 5mA, balance on 15-45mA dynamic change
Product size (MM) L140*W128*T22
Product weight including packaging 470g
Working environment temperature -20 degrees to +55 degrees
Do you need an external power supply? No need for an external power supply, relying on the internal energy transfer of the battery to achieve the whole group balance
Capacitive energy transfer balance board (high precision 1mv, point-to-point energy transfer balance)
Blue Bluetooth status indicator: always on, the link is successful; flashing, the link is disconnected.
Red fault status indicator: always on, internal fault; flashing battery test failed.
Green working status indicator: always on, equalization is completed; flashing and equalization is working.
